Title: Transmitter
Inventor: KUWABARA MUNEMITSU
IPC: H03F1/30
Filed: 1999-08-18
Abstract: PROBLEM TO BE SOLVED: To easily adjust a transmission output by allowing a controlling means to calculate the difference between the level of a signal detected by a detecting means and a prescribed value stored in a storing means and to control a level adjusting means in accordance with the calculated difference. SOLUTION: A directional coupler 8 fetches a part of an output of a power amplifier (PA) 7, and a detection circuit 28 detects it. An A/D converter 10 performs A/D conversion of this detected signal and sends the signal to a control circuit 2'. The circuit 2' checks whether or not the amplitude value of the sent detection signal is the specified amplitude value of an output level of the PA 7 stored in a transmission output level table 29. When the amplitude value of the detection signal is not the specified amplitude value, the circuit 2' makes the attenuation quantity of a feedback side attenuator 9 plus α dB and detects an output of the coupler 8 again. It is possible to easily adjust a transmission output because this operation is repeated until the amplitude value of the detection signal becomes the specified amplitude value in this way.

Title: Torque sensor and production thereof
Inventor: SHOJI MASATO
IPC: H01L41/12
Filed: 1993-09-17
Abstract: PURPOSE:To enhance the output sensitivity of a torque sensor applying the magnetostriction effect of a magnetic alloy. CONSTITUTION:The torque sensor is constituted of a detection coil 4 concentrically wound around an amorphous magnetic alloy 2 so that the gap between the coil 4 and the alloy 2 is 0.5mm or less, a magnetic spacer 8 positioned at both ends of the detection coil and a magnetic yoke 6 receiving the detection coil 4 and the spacer 8. By this constitution, the distance between the detection coil 4 and the amorphous magnetic alloy 2 can be allowed to approach each other and, since a magnetic material is used in both ends of the detection coil 4 and the yoke 6, the leakage of magnetic flux to the outside is reduced and the effect of a disturbance magnetic field is also reduced and, as a result, the magnetic circuit in the periphery of the amorphous magnetic alloy 2 and the detection coil 4 becomes a closed state to a large extent as compared with conventional magnetic circuit. Therefore, the detection coil 4 can sufficiently pick up the magnetic permeability change caused by torque and the output sensitivity of the torque sensor can be enhanced.

Title: Semiconductor device
Inventor: OI KENJI
IPC: H03F3/68
Filed: 1993-09-17
Abstract: PURPOSE:To provide a semiconductor device which contains an output circuit that has high performance and many functions with low power consumption. CONSTITUTION:Plural pieces of output circuit parts 1 are connected in parallel to each other. A characteristic variance value detecting circuit 2 detects the characteristic variance value of the component elements of each part 1. A correction control circuit 3 controls the number of operating parts 1 based on the detecting result of the circuit 2. Thus the number of operating parts 1 is controlled based on the characteristic variance value of the component elements of each part 1. Thus, the sum total of output currents of parts 1 are fixed regardless of the characteristic variance of the component elements of the part 1. Then the ideal output current characteristic is always secured regardless of the characteristic variance of those component elements. Thus it is possible to reduce the noises that are caused by the flowing of an excessive output current. In addition, the through rate can be controlled by adjustment of the signal delay time of each part 1.
